Hi guys, lots of information there, so thanks very much for your input.
Only got the 60w panel to top up the battery that runs the LED lights and water pump. So think the 100amp battery should handle that with a little bit of trickle charging from the panel.
Got 2 sets of portable solar panels for the fridge though, as some have said, they do provide better power input than the fixed system.
My main issue was how to run the cables without them being exposed, and where to run the cabling to the MPPT solar regulator and then to the batteries. I will get some of those glands for sure.
I will try and supply photos of the install as its being done. I'm not that technically savvy, so should be interesting.
I really appreciate everyones input. Great Forum.
